The temperature of the soaking water depends on the type of the raw hide, and is generally preferably 15-18 ℃, for example, the hide is slowly softened below 18 ℃ and bacteria above 20 ℃ are easy to propagate. The soaking time is 5-6 hours, and if the dried skin or dried salted skin with long storage time is soaked, the dried skin or dried salted skin should be softened by physical or chemical method. The soaking time can be 20-24 hours. The skin is required to be soaked, softened and soaked uniformly and uniformly without exposing on the water surface. The temperature and the soaking time are particularly controlled during soaking;
II, secondly: soaking the raw skin selected in the step 1 in water, wherein the raw skin loses water to different degrees in the processes of corrosion prevention, storage and transportation, and collagen fibers of the raw skin are bonded together after the raw skin loses water, so that the penetration and the uniform action of chemical materials in a water supply medium into the skin are difficult. Therefore, the first procedure of leather making is soaking, which can ensure that the dehydrated raw leather can fully absorb moisture to reach a fresh leather state, and lays a good foundation for the chemical treatment of the subsequent procedures;
thirdly, the method comprises the following steps: and (3) soaking the soaked original skin in alkali, and dissolving the mesoglea layer in the skin of the original skin by using alkali liquor so as to separate skin from meat. Removing the subcutaneous tissue layer, the fibrous interstitium and the saponified grease; the moderate loose collagen fiber structure plays a good role in the softness, fullness and elasticity of the finished leather, and the middle layer cells mainly composed of substances such as glue and the like between the thin-walled tissues of the leather and the meat are easily dissolved under the action of alkali, so that the epidermis of the original leather is peeled off;
fourthly, the method comprises the following steps: the alkali-soaked original leather is processed through unhairing and degreasing processes to enable the surface of the original leather to be smooth, a part of the original leather which is easy to change in quality is removed, meanwhile, the phenomenon of plate hardness after the leather is dried is prevented, the split original leather is added into an acid solution to be soaked, alkalinity is removed, the original leather reaches a tanned PH value, and the alkali-soaked and softened fur is obtained. The inner side is laid on the semi-circular wood upwards, the fat, the residual meat and the like attached to the meat surface are scraped by an arched knife, and a layer of thick cloth can be laid on the semi-circular wood firstly during scraping in order to avoid damaging hair roots. The paring is closely related to the next degreasing. Defatting is not favored if the residual fat is too high. The function of scraping the inner part by using the bow-shaped knife also lies in that residual fat in the skin rises to the surface of the skin through extrusion, which is beneficial to degreasing;
fifthly: adding 5-10wt% of plant tanning agent and 1-5wt% of methoxyethyl acrylate into a processing groove 31 on a workbench 1, putting the leather subjected to prior treatment into the processing groove 31 for tanning, setting the pH value of the plant tanning agent between 3-4, setting the temperature between 35-45 ℃ and the time between 7-13 hours, wherein the tanning is a crucial ring in leather processing, connecting collagen groups in leather fibers through trivalent chromium ions in the plant tanning agent to increase the tensile strength and the tear strength of the leather, so the trivalent chromium ion plant tanning agent is used because the hazard of the trivalent chromium ion plant tanning agent is far lower than that of hexavalent chromium ions, the environmental protection is enhanced, and simultaneously, 1-5wt% of methoxyethyl acrylate is added in the tanning process to enable the methoxyethyl acrylate to be crosslinked with the collagen groups in the leather fibers in the tanning process, the methoxyethyl acrylate is used as a modified monomer to increase the cold resistance of the original skin; it should be noted that as a preferred embodiment, the pH value in step 3 is set at 3.5, the tanning temperature is set between 40 and 42 ℃ and the tanning time is optimally between 8 and 9 hours;
sixthly, the method comprises the following steps: the tanned original leather is added into the processing groove 31, and a vegetable tanning agent with the PH value of 5-6 is selected for retanning, the temperature of the retanning is set to be 39-45 ℃, the retanning time is 1 hour, and the retanning is indispensable for some light leathers and has a supplementary tanning effect;
seventhly, the method comprises the following steps: adding a mixed liquid containing 1-5wt% of an X dyeing agent and water into a dyeing tank, dyeing the retanned hide, wherein the pH value is generally controlled to be 4.5-6, and the temperature is controlled to be 40-50 ℃, the step is to endow the leather with certain color, the key is to improve the binding rate and the binding strength of the dye and hide fibers, and the pH value is set to be 5.5, and the temperature is controlled to be 45-50 ℃;
eighthly: the method comprises the following steps of (1) selecting an OES composite fatting agent to fatten dyed leather, filling grease between gaps of degreased leather fibers, and oiling, wherein the step is also implemented to ensure that the leather absorbs a proper amount of grease materials, so that the softness and elasticity of the leather are increased, the leather is prevented from being rigidly cracked, the previous degreasing is to remove the grease in cells, and the step is to fill the grease between the leather fibers;
nine: step S8, drying the dyed and fatted leather in a pasting plate drying mode at the drying temperature of 60-70 ℃ for 30min, drying the leather in the pasting plate drying mode to volatilize moisture in the leather, enabling the leather to shrink and harden, achieving the normal use state and facilitating processing;
ten: selecting different compression rollers according to the requirements of customers, embossing the dried leather surface layer by using an embossing machine, coating the embossed leather surface layer by using a DM-5161 cold-resistant coating agent, extruding the figure elephant required by the customers by using the embossing machine, lubricating the leather surface by using the coating agent through the equipment designed by the scheme, and the like, wherein the leather is protected but has certain use characteristics, and the cold-resistant coating agent is added to enhance the cold resistance of the leather;
